Hi everyone! I'm trying to get Meltano to run in Prefect, using a Docker work pool. I get an error when Meltano is trying to install the plugins. (

No module named pip

). I've tried Meltano versions 3.5.4 and 3.6. Also tried on python 3.12, 3.11, 3.10. Will post logs in the thread.

How do you install meltano in that environment?

it's installed by Prefect, using Pip

Did you set the

venv.backend

at any point? It seems to be creating the venvs for the plugins, but for some reason

pip

is not installed in them. https://docs.meltano.com/reference/settings/#venvbackend

I had not done so and setting it to

uv

before running

meltano install

solved the issue. thanks for the help, was pretty hard stuck on this.

would this indicate that my previous statement

it's installed by Prefect, using Pip

is likely wrong?

Maybe, are there public prefect docs out there for it or could you share what the prefect code looks like for that?
